Product limitation

This product should not be used, applied or recommended:

• In structural glazing applications or where the sealant is intended as an adhesive.
• In areas where abrasion and physical abuse are encountered.
• In totally confined spaces as the sealant requires atmospheric moisture for cure.
• On frost-laden or damp surfaces
• To building materials that bleed oils, plasticizers or solvents – materials such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes.
• In below-grade applications
• On substrates made of polypropylene, polyethylene, polycarbonate and poly tetrafluoroethylene.
• Where movement capability greater than ±50% is required.
• Where painting of the sealant is required, as the paint film may crack and peel
• For structural adhesion on bare metals or surfaces subject to corrosion (i.e., mill aluminum, bare steel, etc.)
• To surfaces in contact with food.
• For use underwater or in other applications where the product will be in continuous contact with water.
